The wilting is probably from transplant shock from when the roots are disturbed the tender root hairs die. If only parts of the foliage are showing wilting, that means that only part of the root system was affected. This is good in contrast to the whole plants 'meltdown'.

To help the plant, cut out the dead portions, do not stress the plant with water or fertilizer, and it may recover. But also with winter coming around, the plant needs to be in an environment more than 40 degrees.
